Said I would post my progress photos of the weld head that I'm working on. Not so much to present just yet, but I'm going to try some initial testing with a small salvaged piston:http://www.ogilumen.com/images/custom/piston.jpgAnd I've got a very solid steel/aluminum base put together from scrap pieces. http://www.ogilumen.com/images/custom/weldhead.jpgMore to follow...

Not to be impertinent, but with the price of the comparable Suncoast units and the number of people going through the trouble of building their own, I'm surprised that someone isn't having a similar welder built in China and that they're not for sale at Harbor Freight. What are the prospects for something like that happening? I've been wanting to repair some nicad battery packs and don't have the resources to purchase or resources and skills to to build my own welder. BTW, I'm really impressed with what you have done.

Instead of using one 3Farad capacitor, what about conecting i parallel large number of smaller electrolitic capacitors. What problems could occur. I am asking this because I read on one forum a post from a guy who used to build CDW machine in this way and it worked ok.

interesting..... could this be done with a diy etching tank then? id be interested if seeing if you can get more boards to be honest, im not sure where in the UK i would go for such workmanship. Excellent product :) Have you got a rough idea when in the new year you would have the new boards?

Hello Fritz,Is it possible to just purchase the programmed microprocessor? I have built the welder according to your schematics, have done all of the tests, and when I got to the last test with the foot switch, nothing happened. I reread your trouble shooting guide and will be testing for the 5V pulse from the processor. I'm hoping that this is the problem. It would be much easier to just replace the processor than to try to find the malfunctioning mosfet.

Nice one Fritz - Just put my order in and busy looking at the schematics. I'm going to take my time with it and go steady as this will be a big step up from what I have done before. The diagrams are very clear and this will make it much easier to complete. It could take me many months but I will get there in the end. Many thanks and eventually I hope to post some photos of the completed welder.

Hello: I was wondering how fast the circuit resets. in other words, how many pulses per second can you make? I want to use this supply for a seam weld using a copper wheel, and I wanted to see how fast you could advance the wheel. I need a continuous weld without gaps

Dan, it all depends on the voltage, pulse timing and resistance you are welding. At about 12v with a first pulse of 0.7ms and a second pulse of 12 ms you should be able to get three welds/ second. This welder was not designed to do continuous welding though and you might have to make changes to the charging circuit though.

I am having a hard time finding a solution to weld piano wire together. This is for an artsy sculptural project, and I just need tacks to keep the wire between 1 and 2mm (approx. 1/16") together. Would you think that your welder handles this?

Fritz, I purchased the plans and pcbs a long time ago. I have a receipt. After purchasing all the materials, my hard drive crashed and I no longer have the instructions or software. Would you please allow me to download it again?

Hey really wonderful post your have shared here, I have bookmarked your blog for the future references. Keep posting the article on this topics, i like to visit your blog once again for future updates .
